memory-master

memory-master is a skill for Claude Code, Codex from sumo1/AI-GAME-COOL. It costs 34 tokens per session (525 once invoked), scanned A, original, Apache-2.0.

A recipe for making card-flipping memory games in which players reveal two cards at a time and find matching pairs. It supports themes such as animals, space, and the ocean for children aged 4 to 10.

In plain words
What is it for?
Use it to create and check memory games with different themes, grid sizes, animations, timers, move limits, score tracking, victory messages, and restart behavior.
Why use it?
It helps avoid common game problems such as allowing too many cards to flip, counting pairs incorrectly, or leaving cards stuck after a failed match.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

memory-master scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

记忆大师

卡片配对翻牌记忆游戏,支持多种主题(动物/太空/海洋),适合 4-10 岁儿童。

何时使用

用户提到记忆、翻牌、配对、卡片匹配、专注力训练等关键词时激活此 Skill。

生成步骤

  1. 根据年龄和难度确定卡片对数(4-6 岁: 4-6 对, 6-8 岁: 6-8 对, 8-10 岁: 8-10 对)
  2. 参考 assets/template.html 的翻牌动画和配对逻辑
  3. 根据用户需求调整:
    • 卡片主题(动物/太空/海洋/恐龙/水果等 emoji)
    • 网格布局(3 列/4 列/5 列)
    • 匹配后的动画效果
    • 是否需要计时器或步数限制
  4. 调用 generateGame 生成完整 HTML
  5. 调用 evaluateGame 检查质量

评估重点

  • 卡片翻转动画是否流畅自然
  • 同时只能翻开两张卡片,不能多翻
  • 匹配成功的卡片保持显示,失败的自动翻回
  • 步数和配对数正确计数
  • 全部配对后有胜利提示
  • 重新开始能正确重置游戏状态
  • 所有卡片在可见区域内,不越界

常见问题

  • 翻牌动画卡死 → 检查 CSS transition 和 JS 状态锁,确保翻牌完成后 isFlipping 标志重置
  • 配对逻辑错误 → 验证卡片匹配判断使用 data 属性而非 DOM 位置,确保同一张卡片不能自我配对
  • 卡片布局溢出 → 使用 CSS Grid 并限制 grid 容器高度,避免 aspect-ratio 导致卡片撑出视口

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
